| 摘要: |
| 为了分析强地物回波产生副瓣干扰,根据毫米波雷达制导系统的实际需求,提出了考虑天线副瓣杂波影响的精确的信杂比模型,并通过仿真计算得到了考虑副瓣影响的雷达的最佳搜索角。文中所提出的方法对精确预测雷达信杂比有重要的指导意义,同时对综合设计雷达中天线的性能指标也有重要意义,可提高整个雷达系统的性能。 |

|
| () |
| Abstract: |
| The exact signal-to-clutter model including antenna sidelobe effect is presented in this paper.The strong ground clutters caused by antenna sidelobe can be predicted by this model in the millimeter wave(MMW) radar guiding system.The optimized searching angle is found by this model.So the method presented in this paper is very important to predict the signal-to-clutter ratio and design the antenna.It can improve the performance of the MMW radar system. |
